#: Frame reference
- Positions derived by OPUS or DigiFarm (Transit Works, A&D) RTN using reference frame 83-11
- Positions derived by OPUS (prior to 2012) or Seiler RTN using reference frame 83-CORS.
- Positions derived from in-ground control using 83-HARN.
- Positions derived from in-ground control using pre 83-HARN reference frames.
- Positions derived by RTK from an autonomous base position not directly tied to a reference frame.
Such positions must be relative to accurate positions observed on the same day or from the same base position on different days.
